Specification of Lettersyatent. Patented Nov. 28,1911.

Application filed. September 9, 191i). Serial No. 531,277.

' the provision of a package adapted to preserve the contents in substantially the same condition for an indefinite period of time. rilhe package comprises three wrappers, namely, an inner wrapper, an outer wrapper and an intermediate wrapper, all of said wrappers being composed of material which is adapted to be folded, such as paper 1n ,various forms.

rlhe special use for which the wrapper is designed is for the packing of articles of food, which should be preserved in either a moist or dry condition. f

Of the accompanying drawings which illustrate a package constructed in accordance with this invention: Figure 1 represents a longitudinal vertical section of the inner wrapper in folded condition. Fig. 2 represents a transverse section thereof. Fig. 3 represents a longitudinal vertical section of the intermediate wrapper in closed condition. Fig. 4 represents a transverse section thereof. Fig. 5 represents a longitudinal vertical section of the outer wrapper closed and sealed. Fig. 6 represents a transverse section thereof. Fig. 7 represents a perspective view, portions being broken out,

' of a package comprising the three wrappers,

one within another.

rllhe same reference characters indicate the same parts wherever they occur.

The inner wrapper, intermediate wrapper and outer wrapper are indicated respectively at 10, 11 and 12. The contents of the -package are indicated at 13. rlhe outer wrapper 12 is composed of relatively thick, stiff cardboard adapted to withstand a fair degree of pressure without and to protect the contents against such pressure. The intermediate wrapper 11 is composed of absorbent material, and the inner wrapper is composed of thin, flexible, waterproof material such as paraiiined paper. The materials thus used possess advantages for both moist and dry contents. If the contents be moist, such as pickled fish, the moisture is eiciently imprisoned by the waterproof material and the escape of moisture is therefore' prevented. lf the contents be relatively dry, such as farinaceous food stuffs, the admission of moisture from without is prevented not only by thewaterproof wrapper 1() but by the absorbent wrapper 11. rlhe function of the absorbent wrapper 11 is not primarily to give strength to the package, but merely to arrest the admission or escape of moisture.

'llhe marginal portions of the waterproof wrapper 10 are folded inwardly so as to overlap each other upon the contents, as indicated at 14, thus entirely inclosing the con tents and .forming a substantially dust-proof Iand moisture-proof container.

rl`he intermediate wrapper is preferably made in the form of a box having flaps 15, 15, and 16, 16, which form a cover when folded. As shown by Figs. 3 and 4f, the flaps 15, are folded first, and the flaps 16 are then folded upon the flaps 15. The flaps 16 are preferably of sufficient size to overlap each other, thus providing an absorbent material entirely inclosing the waterproof wrapper. rlthe outer wrapper 12 is also made up in the form of a box, and includes flaps 17, 17, and flaps 18, 18. As shown by Figs. 5 and 6, the flaps 17, 17 are folded inside the flaps 18, 18. 1n order to avoid external shoulders and to a'ord a substantially smooth external surface, the flaps 18 are so proportioned as to meet in edge to edge relation, as shown by Fig. 6, instead of overlapping each other. The fiaps 18,18, however, overlap and inclose the flaps 17. Although each of the wrappers 11 and 12 requires but one set of flaps such as those described, it is convenient to provide them with two sets of flaps on opposite sides of the package, this duplicate construction being illustrated. V

rll`he flaps of the outer wrapper may be secured by a band 19 of paper or other 1naterial extending around three or four sides of the package, preferably in a direction parallel to the meetingY edges of the'flaps 18. If the band be secured by some adhesive substance, the package is eliciently sealed The flaps may be readily released by scoring 'an outer wrapper, and an intermediate 19 along the line of the meeting/edges and between' the ends of the flaps 18 andl the flaps 17. 1 v

If the package thus made up contains food of a very moist nature, such as pickled fish', the moisture which would evaporate between the folds 14 would be absorbed by the intermediate wrapper 11 and lthus be prevented from soiling the external wrapper. This is an essential feature of the invention, inasmuch as itis extremely desirable to maintain aclean and neat appearance for the external Wrapper.

I claim:

A package comprising an inner Wrapper,

Wrap er, said inner wrapper being compose of thin flexible waterproof material, and wholly inclosing the contents so as t0 prevent the passage of moisture, said intermediate wia per wholly inclosin the inner wrapper an being composed ofg absorbent material, and said outer Wrapper being composed of relatively thick stiff material wholly inclosing the intermediate wrapper. Y In testimony whereof I have aixed my signature, in presence of two witnesses.
